Question 1

Guideline with selection criteria

Accepted Answer

Guideline with selection criteria for the individual “tailor-made system”
1	Medium	Gas; hydraulics (oil, water …)
2	Pressure type	Relative pressure, absolute pressure; differential pressure
3	Operating mode	manual; semi-automatic; fully automatic
4	Measuring range	2.5 mbar up to 10,000 bar
5	Accuracy	0.003% MW to 1.0 % EW
6	Use	stationary in the laboratory; mobile in operation; mobile for on-site use
7	Application	Calibration of sensors with measuring range: …. / Accuracy: ….
8	Calibration certificate	DAkkS calibration certificate; factory calibration certificate
9	Interface	RS232; IEEE; USB; Ethernet
10	Software	Excel calculation; calibration software; database function; special functions
11	Pressure supply	Vacuum pump; compressor station; pressure distribution with reduction
12	Accesories	Dirt separators; media separators; pressure adapters and hoses
